Compatibility of Roadmaster 5211440-1B with 2020 Jeep Grand Cherokee  

Updated 08/12/2025 | Published 04/29/2020

Question:

I purchased a Roadmaster tow bar baseplate P/N 521440-1B from you in the past for my 2015 Jeep Grand Cherokee. Now I am upgrading to a 2020 Jeep Grand Cherokee Limited. Will my existing baseplate fit the new 2020 Jeep?

Expert Reply:

Yes. The part number you referenced is basically the # RM-521440-4 which is compatible with 2020 Jeep Grand Cherokee Limited. That part number replaced the 5211440-1B so the fit is identical.

If you had the SRT-8 or Trackhawk model it would not be compatible but the limited is a fit.

I have the roadmaster tow bar kit PN 521440-4 that I pulled from my 2017 grand cherokee. I want to install it on my new 2023 Dodge Durango. Any issues before I dive into the installation?

@Steve What you have unfortunately does not fit your 2023 Durango. Instead you'd need the part # RM26VR which was designed to fit that generation.
